He seems pretty ruthless; willing to do anything to make money. Running a spam operation is a questionable act. These same attitudes and acts of moral wrongdoing seem to perpetuate along the operations of his current company (Airbnb). What's to stop him except of course the risk of facing criminal legal charges?
I don't think ruthless because I don't know if he physically hurt anyone, but its a secret how he got off FBI top list with no consequences whatsoever.
Perhaps high connected friends - who knows? But there are people sending 1/1000th of spam volume he did and are doing 10 years in jail, so ultimately that's where I think Nathan belongs.
